Justin Bieber invites ten lucky girls back to his house in Rio where he woos them with child-like feast of 'chocolate, crisps and chicken nuggets'

He's an international pop star worth an estimated $130 million - but there's no forgetting Justin Bieber is still a teenager who evidently enjoys the simple things in life.

Following an evening out at a nightclub, the 19-year-old is said to have taken a bevy of lucky young ladies back to his rented mansion in Rio, Brazil on Sunday night, where he treated them to a very un-glamorous feast.

Upon signing a confidentiality agreement and handing over their mobile phones, partygoers were treated to a very child-like menu of chicken nuggets, chocolate, lollies, chips and peanuts.

Showing his age: Justin Bieber may have had quite the wild weekend in Rio, Brazil, but according to one lucky clubgoer who was invited back to his house on Saturday night, the scene awaiting them was positively child-like

Marina Binimeliz, an 18-year-old student, has revealed that she was one of 10 girls chosen by the singer to partake in the sugar and carb-laden festivities after talking her way into the star's private room at Zax nightclub via a smitten translator.

'He warned me not to hug or overwhelm Justin. So I kissed him the cheek as a greeting,' she recalls.

Heading back to his home a short time later, guests were met not with overflowing bottles of alcohol, raucous music and diva-like antics, but rather a more sedate atmosphere.

'There were lots of snacks spread on tables by the pool, on the verandah and in the lounge area,' the Daily Mirror reports the teenager as saying.

'We ate peanuts, Doritos, crisps, chicken nuggets and slices of pineapple. Justin liked the Brazilian Misto Quente, which is toasted bread, egg, ham and cheese. There was lots of chocolate and Haribo sweets.'

'This was a fantastic, perfect moment for me': The teenager gushed that her idol 'put his arm around my waist, squeezed me and kissed me on both cheeks' as she left the following morning

The pretty brunette went on to reveal that she saw Justin 'stuffing himself with Toblerone' during the evening, but while the house smelt of marijuana, she didn't witness the Never Say Never hitmaker smoking.

'We all had to sign contracts saying we wouldn’t take any photographs and, if we did, we agreed not to publish them,' Marina explains. 'I was only given my phone back when I left.'

She added: 'I tried to take a picture of the contract, but they whipped the phone out of my hand before I could do so.'

At one point, Marina alleges that Bieber rather embarrassingly got up and danced to one of his own hits, before things 'got a little crazy' and he 'jumped onto a wall and yelled, "I'm the king of the world!"' a la Jack in Titanic.

According to the youngster, Justin called it a night at 9am that morning, when he offered the girls coffee.

'We weren’t told to go exactly,' she explains. 'Justin just said, "I’m tired. I think I need to go to sleep."

'He came to me, put his arm around my waist, squeezed me and kissed me on both cheeks. He wished me a good night and told me I was very cute. This was a fantastic, perfect moment for me,' she gushed.

Of course, this comes just a night after the singer unsuccessfully attempted to sneak out of brothel Centauros reportedly accompanied by two prostitutes.

Meanwhile, it's been reported by
Newser.com that Justin is investing $1.1million into a social network
aimed at teenagers called Shots Of Me.
